Common hippopotamus

Hippopotamus amphibius

Also calledKiboko (Swahili) · Imvubu (Zulu) · Erinmi (Yoruba) · Faras al-nahr, 'river horse' (Arabic) · Hémǎ 河马 (Chinese)

A huge, semi-aquatic grazer that spends its days in rivers and lakes and comes ashore at night to graze. Despite its plant diet it is one of Africa's most dangerous animals to people.

The hippopotamus, often shortened to hippo, further qualified as the common hippopotamus, Nile hippopotamus and river hippopotamus, is a large semiaquatic mammal native to sub-Saharan Africa. It is one of only two extant species in the family Hippopotamidae, the other being the pygmy hippopotamus. Its name comes from the Ancient Greek for "river horse" (ἱπποπόταμος). Wikipedia

What it can do

  1. iSecretes a red 'blood sweat' (hipposudoric acid) that acts as sunscreen and inhibits bacteria
  2. iiHolds its breath for about five minutes, walking or bouncing along river bottoms instead of swimming
  3. iiiMoves huge amounts of grass-derived nutrients into rivers in its dung, fuelling fish and other life
  4. ivOpens its mouth to about 150° to show tusks up to ~50 cm long

Marginalia

In ancient Egypt the hippo goddess Taweret protected women in childbirth, and blue faience hippos were placed in tombs. Many scholars think the Behemoth of the Book of Job was inspired by the hippopotamus.

Curiosity

Pablo Escobar's four hippos in Colombia have grown into a wild herd of over 150, now the largest hippo population outside Africa.
